Emotional intelligence (EQ) refers to effectively blending thinking and feeling to make optimal decisions. Research in the last 20 years has shown that emotions play an important role in decision making and behavior. EQ is key to professional success and is essential for building effective relationships, teams, and reputation in business. It can be improved through assessing one's strengths and weaknesses, committing to develop a specific area, and with coaching support over time. Businesses can build EQ into their strategy through vision/values, talent management, training, performance reviews, and community contribution.
